Gals, here is a new "man created stone" that is made in Mexico. Pulverized carbonate rock is taken and dyed into various colors with pigments, put into layers then stabilized with a polymer to create "Rainbow Calsilica". It usually comes in a rainbow of colors, but this 3 pc. set comes in black and white! These stones looks unique but fabulous, (in my book!) The oval disks 12x17mm are striped lengthwise, white ceramic rounds measure 9mm, and the jet glass is 8mm. Also the findings are black matte metal that is also a new trend. The prong set pendant has also a black matte setting of 19x26mm and has a matte toggle clasp w/a rhinestone accent on it. The set also has a wonderful bracelet as well. I've got a jet black crystal ring on the site. I am sure this 19 1/2" necklace set will become a regular choice in your jewelry accessory wardrobe! Black matte fish-hook styled drop earrings are included of course! If you have allergies please note that it has been treated for allergies!
